• Liner Paper Liner Paper is used in the production of Corrugated Board and Cartons.
• Extensible Sack Kraft Paper Extensible Sack Kraft Paper is highly durable and resistant to impact. Hiang Seng manufactures and supplies this product to manufacturers of bags for the cement, animal food, plastics and chemical industries.
• Corrugated Medium Paper Corrugated Medium Paper is suitable for making the fluting in the manufacturing of Corrugated Board in between the Liner Paper as described above.
• Corrugated Sheet Board Hiang Seng manufactures and supplies single wall, double wall Corrugated Board.
• Corrugated Cartons Hiang Seng manufactures and supplies two kinds of Corrugated Carton. The Regular Slotted Carton (RSC) is printed, creased, slotted, glued and folded into the finished product. The print contains logo, image of goods for advertising, and other necessary information such as using instruction. This type of box is designed to protect goods during stacking in warehouse and during transportation. The other kind of carton is Die-Cut Carton which is made by die-cutting the corrugated board into different shapes and sizes, printed with advertising materials, storage, and other necessary information. This type of box is designed for transportation of light weight product such as instant noodles, or self supporting product such as drinks in glass or plastic bottle.
• Multi-wall Sack Kraft Paper Bags We supply three and four layer Multi-Wall Sack Kraft Paper Bags to the cement, animal food, plastic and chemicals industries.
• Gummed Paper Type This product is primarily used for sealing Corrugated Board Cartons and Boxes.
• Paste Valve Paper and Sub Bag Paper Type Hiang Seng supplies Paste Valve Paper and the paper used to seal the base of Multi-Wall Sack Kraft paper bags (Sub Tape Paper). These products are primarily used in the manufacturing of Multi-Wall Cement Sack.

Over the years, Hiang Seng has invested in first class machinery for paper making, corrugated carton and Multi-Wall Bag converting. Each process will be controlled with latest automation and computer programming to reduce variation in process and ensure consistency of final product quality.

Thanks to advance recycling process and paper machine technology. More and more recycled fiber can be used as raw materials while specification of paper can be maintained. This will reduce use of fresh pulp and preserve forest.

In paper machine we have employed latest 0.5 mm screening system to classify and screen clean fiber to use in multi layer paper machine. Hydraulic Headbox with dilution control can distribute fiber more evenly to achieve better cross machine basis weight profile. Shoe Press is used in Press Section to give better strength of paper while maintain caliper of paper which will improve stacking strength of paper. All machines are equipped with Size Press Unit where starch is applied in onto paper surface and penetrate by two roll nip. It improves paper strength both stacking and bursting properties. The process is controlled by QCS to maintain paper basis weight and moisture profile to be within specification.

Our corrugating plants employ fast running 2.5 meter corrugators and various converting machine i.e., Flexo Folder Gluer from France and Japan, Flat Bed Die Cutter from Switzerland, Rotary Die Cutter from China/USA. Finish carton is tested by International Standard Tappi/ISO and certified before delivery to customers. Our carton has been proven in the market for its high stacking strength and rigid board suit for automatic packing machine.

Our target is to produce the highest quality and strength of paper and corrugated carton without any compromise to the quality from the use of recycled fibre. Up to date equipment and process will consistently be employed to ensure top class product quality while our reliable logistic service and timely delivery will benefit product and cost management to our customers.

Sustainability becomes a global interest in the recent years. People are aware of the use of limited natural resources. In paper industry, recycling is more and more popular as raw materials to replace the use of virgin pulp. At Hiang Seng, we continue to increase the recycling ratio to achieve full recycling for all grades of paper.

Environment and renewable energy is another area of our interest. In the Paper Mill we successfully installed the Reactor from Europe for effluent treatment by anaerobic bacteria. The bacteria digest contaminants in effluent and produce methane gas as by product. Effluent from the Reactor will have 75% lower in COD which requires much lower electrical power in the aerobic treatment, while methane gas becomes fuel for steam boiler. The system preserves the environment, reduces the use of limited natural resources such as coal and conserves the energy at the same time.
